Vertical jet-flow ultrasonic soldering tank - ACSS series - ACSS-KV


This device is a jet-flow ultrasonic soldering tank with ultrasonic vibrations applied vertically. Main application is for products that require soldering from below, or inside a tube-shaped structure. It enables flux-free soldering, eliminating excessive flux and rendering cleaning process useless.

Soldering tests may be performed on customer's samples.
Please feel free to ask us for more details.
